· Multi-level PWM control mode, providing sine wave current output. Low common mode voltage and du/dt, no special requirement for the motor and cable. When upgrading the equipment, it is not necessary to replace the motor.
· Multi-pulse rectifier can effectively suppress higher harmonics and harmonic ratio is far less than the national standard (THD <5%).
· Various motor control technologies: drive asynchronous motor and synchronous motor (permanent magnet synchronous and other excitation synchronous)
· System components: main control chip of drives integrates the most advanced and mature ARM core processor; the control of each power unit is realized by a large FPGA programming chip; the main control board can directly communicate with the IO board to realize the functions of DI/DO and AI/AO, with fast port response, without PLC.
